A large, shallow, hot magmatic heat source is present beneath Alid volcano. Fumaroles and boiling pools are distributed widely on the north half of Alid. Most of the thermal areas are located at elevations between about 460 and 600m. Thermal areas do not occur within the flat pumice covered areas in the summit depression.
